The Circle of Life Hormonal Regulation. There are several factors that can trigger the hormones that cause senescence in plants. Some are environmental factors, such as drought, or the changing of seasons. Senescence can also be triggered in only a small area of the plant. This might happen if the plant became infected with a disease.

Ageing Ageing (British English) or aging (American English) is the process of becoming older. In the narrow sense, the term refers to biological ageing of human beings, animals and other organisms.In the broader sense, ageing can refer to single cells within an organism (cellular senescence) or to the population of a species (population ageing). DNA damage theory of ageing: Genetic damage has two types. 2  Mutations are damages to the DNA sequence, while epimutation is damage to the DNA scaffolding which regulates gene expression in the cell. 3  Both ultimately harm our health by causing abnormal gene expression.

- Escape From Senescence There are two independent events that frequently occur allowing cells to evade or overcome senescence, mutation of p53 and the activation of telomerase. p53 mutation is one step in the transformation of cells promoting cells to undergo unregulated cell growth. It is also a step in the evasion of senescence in which cells no longer respond to the senescence signals and thus continue to grow. However, telomeres continue to shorten with each cell division past the senescence barrier.

Declining a Latin Noun Latin For Dummies. They say that old Latin teachers never die — they just decline. Whether this is true of teachers, declining and declension are facts of life that all Latin nouns must face. A declension is a group of nouns that form their cases the same way — that is, use the same suffixes. To decline a noun means to list all possible case forms for that noun. Latin has five declensions; this article looks at the first two. First-declension nouns. The first noun group that uses the same suffixes to form case is, not surprisingly, called first declension. All the nouns in the first declension use the endings shown in Table 1 to indicate case in a sentence.

In the broader sense, ageing can refer to single cells within an organism (cellular senescence) or to the population of a species (population ageing). In humans, ageing represents the accumulation of changes in a human being over time, encompassing physical, psychological, and social change. Reaction time, for example, may slow with age, while knowledge of world events and wisdom may expand.

Aging Aging, progressive physiological changes in an organism that lead to senescence, or a decline of biological functions and of the organism’s ability to adapt to metabolic stress. 1  Aging takes place in a cell, an organ, or the total organism with the passage of time. It is a process that goes on over the entire adult life span of any living thing. Gerontology, the study of the aging process, is devoted to the understanding and control of all factors contributing to the finitude of individual life.
